SS-EN-ISO-7783 › Paints and varnishes - Determination of water-vapour transmission properties - Cup method (ISO 7783:2011)
The following bibliographic material is provided to assist you with your purchasing decision:
This International Standard specifes a method for determining the water-vapour transmission properties of coatings of paints, varnishes and related products.It supplements ISO 12572. As far as possible, the procedure, the defnitions and the calculations have been taken over from ISO 12572. It is recommended that ISO 12572 be consulted, if necessary, to obtain a better understanding of the procedure specifed in this International Standard.Water-vapour transmission rates of more than 680 g/(m2·d) (i.e. water-vapour diffusion-equivalent air layer thicknesses, sd, of less than 0,03 m) will not be accurately quantifed by the test method described in this International Standard.
